Abstract

Nutrients are a fundamental component of any aquatic food web. However, anthropogenic activities within a watershed may alter nutrient loads to aquatic ecosystems - typically increasing loadings - and cause undesired changes to food webs and negatively impact ecosystem health. Great Salt Lake (GSL) is the largest saline lake in the western hemisphere. The lake supports a unique foodweb and is a critical ecological, economic, and cultural resource. Urban and agricultural land uses, point source discharges, and water extractions all occur within the GSL watershed. The potential impacts of these activities are further complicated by the construction of road and railroad causeways which have segmented the lake into four relatively distinct bays. Each of these human alterations provides the potential for deleterious changes to nutrient loading or cycling and foodweb impacts in GSL.
